Suppose the line y=5x-4 is tangent to the curve y=f(x) when x=3. If newton's method is used to locate a root of the equation f(x)=0 and the initial approximation is x1=3, find the second approximation x2.
can someone help me with this one? thanks
Now you nothing of the true function value at nor its derivative so with the given information no further step is possible, but this would only be the exact root if , which we are not told.
